Question:
a. Propose a structure for the compound.
b. Assign the 1H NMR and 13C NMR spectra for each compound
On the next four pages are MS, IR, and 1H and 13C NMR spectra of compounds A, B, C and D. The molecular formulas are given. Use these spectra to propose structures forA, B, C and D. For each compound do the following:
a. Propose a structure for the compound.
b. Assign the 1H NMR and 13C NMR spectra for each compound.
Note: if you are not confident with your proposed structure, try your best to identify as many as possible functional groups (fragments) on MS, IR, 1H NMR and 13C spectra to gain credits.
Compound A (C7H12O)
(1) Mass Spectrum
